Difference between Aluminum and Copper Wire

When it comes to wiring, there are a few different types of materials that can be used. Copper and aluminum are two of the most common, but what’s the difference between them? Let’s take a look.

What is Aluminum Wire?

Aluminum wire is a type of metal wire that is made from aluminum. Aluminum is a lightweight metal that is known for its durability, making it an ideal material for use in wire products. Aluminum wire is commonly used in electrical applications, as it is an excellent conductor of electricity.

Aluminum wire is also used in jewelry making and other crafting applications. It is available in a variety of gauges, or thicknesses, to suit different needs. Aluminum wire is a versatile product that can be used in a variety of applications.

What is Copper Wire?

Copper wire is a type of electrical wire that is commonly used in homes and businesses. It is made of a conductor, typically copper, that is surrounded by an insulator, typically plastic. Copper wire is used to carry electrical current from one point to another. It is often used in wiring systems, electrical panels, and electrical devices.

Copper wire is an efficient conductor of electricity and is resistant to heat and corrosion. It is also a flexible material that can be easily bent and shaped. Copper wire is an essential component of many electrical systems and is widely used in the construction of homes and businesses.

Difference between Aluminum and Copper Wire

Aluminum and copper wires are both excellent choices for electrical wiring applications. Both metals have a long history of safe and reliable use in a variety of settings. However, there are some important differences between these two materials that should be considered when making a selection. Aluminum wire is lighter than copper wire, making it easier to work with. Aluminum is also a more efficient conductor of electricity than copper, meaning that it can carry more current for a given size wire.

However, aluminum wire is more susceptible to damage from voltage spikes and needs to be larger in diameter to carry the same amount of current as copper wire. Copper wire is more expensive than aluminum wire, but it is also more durable and less likely to be damaged by electrical surges. When choosing between aluminum and copper wire for an electrical project, it is important to consider the specific needs of the application.


Aluminum and copper wiring have different properties that make them suited for different purposes. When it comes to electrical wiring, aluminum is a better choice for overhead power lines while copper is more often used in residential applications. If you’re not sure which type of wire to use for your next project, consult with a professional.
